Flat and oval-shaped end with medium to long hairs.
Good for: blending, soft rounded edges like flower petals. this brush is sort of a combination of the rounds (because they can be used for detail) and flat (because they can cover more space than round).
Flat, spread hairs.
good for: natural hairs are good for smoothing, blending, and feathering. synthetic hairs are better for textural effects, clouds, and leaves on trees. for acrylics, use strong and sturdy one, otherwise the hairs will clump when paint is added.
